Afraid of losing Dean, Sam makes a deal with a demon. But taking Sam to hell wasn’t exactly what the demon has in mind. Now the demon blood inside him is burning, destroying him. Dean is the only thing that is keeping Sam sane. But for how long?

Okay, here's another Supernatural story by me. I thought of what might happen next in Season Three, then I thought of this, which probably wont end up happening but I wanted to write it anyway. So you might not want to read this if you haven't watched to the last episode and don't know what's happened. And I'm not sure if this is going to be Wincest or not...so guess you're just going to have to read and find out huh?

A Deadly Deal with a Demon

Chapter One: The Beginning

"Hey, Sammy, where are you going?" Dean Winchester asked as his brother as Sam opened the door of their hotel room. Sam turned back to look at his brother.

"Dean? I thought you were asleep," Sam said as he glanced back out at Dean's '67 Chevy Impala and tightened his grip on the car keys in his hand, not sure how he was going to leave now.

"Not anymore. So, where are you going?" Dean repeated, sitting up in his bed and looking over at Sam through sleepy eyes. Sam shrugged and replied with, "Just getting a bite to eat."

"Oh, alright," Dean sighed as he lay back down on his stomach, accepting this answer. "Get me something too?"

"Yeah, uh, sure," Sam said with a small smile as he started backing out of the room. "See you in a bit."

"Uh-huh," Dean muttered, burrowing his head in his pillow, giving into sleep. "But be careful."

"No problem," Sam said and closed the door behind him. He rolled his eyes as he headed to the car. "It's not like I'm not ten anymore Dean."

Sam opened the trunk and sorted through the items, taking out the needed material: a small box, one of his fake IDs, and a few other things. He walked down the road a ways until he got to the crossroads. As quick as he could, he dug up a large amount of both gravel and dirt and placed the container of things in the hole. Covering the items, he stood and looked around, waiting for the demon. He cracked his knuckles impatiently, waiting for the demon and wondering if he even did this right.

"Well, well. Sam Winchester."

Sam took a breath and turned around slowly to see a reasonably attractive girl standing there, grinning up at him. He guessed that this must be the crossroads demon.

"I want to make a deal."

The demon still grinned and nodded. "I know. That's why everyone summons me after all. Let me guess, Sammy is all heartbroken over Dean's one-year lifespan and wants to save his big brother no matter what it takes. Let me know if I get close."

"You're the one that made that deal with Dean right?" Sam asked, hoping he'd gotten the right demon. Though how many there were like her, he wasn't sure. One thing was certain though; he didn't like how this demon girl knew why he was here. It made him feel a little to defenseless.

"Yes, of course. I'm very interested in your family Sammy. Of course, I'm not the only one who knows the Winchester name, many do. But I'd like to think of myself as an insider of the Winchester affairs," the demon said as she walked closer to Sam. She put a hand on his cheek and he shivered from the frozen touch. "After all, I know all about you and your brother."

"Then you'd know that I would do anything to save him," Sam stated, refusing to back away from her touch. He didn't want to show any fear, not to a demon. "And I will. Name your price."

The demon's grin grew and she shook her head with a slight laugh. "Sammy, Sammy, Sammy. What makes you think I'd want anything of yours?"

"Because if you know so much about me, then you should know that I'm special," Sam explained, keeping back another shiver as she touched the other side of his face with her other hand and pulled his head down slightly to look into his eyes.

"You're right Sammy. You are special. Much more so then Dean. Which means that I can't just let you walk out of here with a year to live. You're worth too much for that."

"I'd appreciate it if you could just call me Sam. Only Dean calls me Sammy. Oh, but I'm sure you already knew that," Sam said and the demon frowned.

"Fine, Sam, but that still doesn't resolve anything. What do you have to offer me in return for your brother's life?" the demon asked, taking her hands away from his face and starting to circle him. "Want a trip to Hell right away? I can do that. And your brother lives a long healthy life."

"I want to stay with Dean."

"Now, now. You can't have everything you want, right? The world just doesn't work that way."

"And neither does Hell it seems," Sam said as he ran a hand through his hair, thinking of a solution.

"Ha, I like you Sam. Sure Dean has the looks, but you have such an adorable personality," the demon said from behind him, running a hand up his bare arm, sending shivers down his spine. "And trust me, it never hurts to have a demon on your side."

"If you say so," Sam said with a sigh, stepping away from the demon then facing her. "I just want my brother to be okay. So could you just name your price?"

The demon seemed thoughtful, running her eyes up and down Sam. She bit her lip as an idea came to her head, one that was even better then taking Sam down with her to Hell. "So, you want to stay with your brother? For more than just a little old year? I think I know just the deal."

The demon grinned. "Well, I can't tell you. If I did, that wouldn't be any fun now would it."

Sam frowned and shook his head. "No, if you don't tell me, then I can't trust you. And no deal."

"Fine," the demon said and turned to leave. "Just make sure you start saving for Dean's funeral now. That junk is expensive."

"Wait," Sam said, and the demon stopped mid-step. She grinned, though Sam couldn't see it. He and his brother were so alike; it almost made this too easy. "Please, wait. Can't you tell me anything about the deal? How long will I have with Dean?"

"Oh, you'll have as long as possible. If you agree to this deal, I swear not to kill either of you ahead of your time," the demon answered with the same grin. "So how about it Sammy? You get to keep your life and Dean gets to extend his. All for just one little deal."

Sam sighed. He knew the demon wouldn't give away whatever big secret this was, and it wasn't going to be good either. But at the thought of saving Dean, Sam really could care less about the consequences."

"Fine, you save my brother and I'll do whatever you want so long as neither me or Dean goes to Hell."

"Then it's a deal," the demon said, grabbing the back of Sam's neck and bringing him down into a harsh kiss.

"Sam?" Dean muttered as he opened his eyes at the sound of the door opening. He yawned and sat up slightly, seeing Sam close the door, a fast food sack in one hand. Another yawn slipped past his lips as he asked, "Didja gimme sumptin'?"

Sam raised an eyebrow at his sleepy brother and couldn't help but laugh. "Dude, I can't believe I just understood that. And, yeah, I got you some fries and a burger, alright?"

"Cool," Dean said getting out of bed slowly. He glanced at the clock and saw it was a little past four in the morning, way too early for him. But that food smelled too good to pass up.

"You know, we're going to die a lot earlier than we should putting all this grease and salt into our bodies everyday," Sam complained with a smile, picking up a few French fries and stuffing them into his mouth.

"Ah well, doesn't matter much to me," Dean said with a shrug, nervousness mixed with a humorous tone. "Don't have that long to worry anyway."

Sam opened his mouth to say otherwise but stopped himself. Dean would kill him if he knew what his little brother had done for him, and Sam knew it. So he decided that he wouldn't tell Dean until the demon put whatever plan she had into motion, and maybe not even then.

"I told you I'd get you out of it Dean, so don't think like that," Sam replied safely. His brother wouldn't question that. Dean knew that Sam wanted to save him, but Sam knew that Dean wouldn't expect Sam to do what he did and make a deal with a demon.

"Right, sorry Sammy," Dean said and bit into his hamburger. Sam watched his brother carefully, secretly celebrating that he'd still get to eat with Dean even after a year. That he'd still get to just sit here and watch his big brother scarf down a hamburger.
